where we used (REF ).
This means that in our case we have the exponent \(n=1\) .
It was also proposed [1]}, [2]} that (in units where \(\kappa _{10}=1\)  and in Einstein-frame) the distance \(\Delta \)  and the scalar curvature \({\mathcal {R}}\)  scale with the distance \(D\)  in field space as
\(\Delta \sim e^{-{\frac{\delta }{2}} D}\,,\qquad |{\mathcal {R}}|\sim e^{\delta D}\ \)
